How to make sweet potato egg breakfast casserole

This tasty morning dish includes a good amount of steps, but they're all simple and straightforward. Start by chopping and sautéing the vegetables, and then put them in a casserole dish. Repeat, this time with the turkey, add the egg and cheese mix, and bake!

Below is the step-by-step breakdown:

First, chop the vegetables as directed and grease a 9x13 casserole dish.

In a dutch oven or large sauce pot, add avocado oil.

Once hot, add onion, green pepper, and sweet potato and cook for 8-9 minutes (or until soft).

Throw in garlic for the last minute or two and sauté. Remove the veggies and lay them in the bottom of a 9x13 pan.

Next, add the turkey sausage to the same dutch oven and sauté until fully cooked. Add the veggies and stir to mix.

In a separate bowl, whisk the eggs, milk, thyme, salt, pepper, and cheese.

Pour the egg mixture over the veggie and sausage mixture and stir evenly until dispersed.

Bake for 40-45 minutes, or until the center is firm. If it starts to brown halfway through, cover with foil.

Finally, let cool for 15 minutes and serve!

Substitution Tip

Sweet potato egg breakfast casserole is pretty versatile in that you can use a number of ingredients to achieve an equally delicious result. Here are some simple substitutes that you may want to try!

Yellow onion: If you want a more potent onion taste, try using a red onion instead.
Green pepper: Your green pepper can be swapped with a red, orange, or yellow pepper for a similar result.
Turkey sausage: If you'd like, you can swap the turkey sausage with the sausage of your choice, whether chicken, pork, or something else. A plant-based alternative will work too!
Milk: As mentioned above, any type of milk will work. You can use regular dairy, or you can go with almond, cashew, oat, or whatever you like!
Mozzarella cheese: Finally, I love to use mozz cheese in this dish, but many types will be tasty! You could use cheddar, pepper jack, or even Swiss.
